This invention relates tob'arricades such as: are generally used by contractors 1n road construct1ons,-.excavations and the like; and it -1s primarilyan object of the-invention to pros E vide aidevice ofthis'kind'which, when not'in use, may be folded or compacted "to occupy a: minimum ofqspace and which, when extended fonuse, is so arranged-as to effectively maintain-itself in proper; placement and particu larly to withstand the wind: a

An additional object of thein-yention is to provide a device. of a this kind I comprising. a

standard having. associated therewith bracing membersssaid 'bracing members being capa- 1 blecof adjustment into different positions as, the; occasions; ofipracti'ce may. require" and wherein means-are provided forueifectively maintaining said .bracingimenibers' in desired position with respect to the standard;

Figure 6is an enlarged fragmentary view in perspective illustrating an attachment for i use in connection With a barricade.

a As herein disclosed; our improved bani-: cade' comprises a standard 1 of' desired length 00 and stability" and which is provided at its bottom extremity with" a cross; member: 2. This cross member Q-eXtends a mat'erialdistan'ce beyond the opposite sides of the stand ardl and :is at: right angles-thereto and'gacts 1 6 as a'means to assure the desired maintenance- I of theupri'ght or' standard 1 in working'position. Theilower edge of lithis cross member a 2 is substantially iflush with the adj acent or i bottom endface of the standard 1. 70 The upper end portion of the standard "1 has suitably anchored or afi ixed thereto a plate '3 having its' central portion extending I beyond the opposite side faces of the standard l 'and :withthe upper and lower; ortions' l6 of each sidemargin of the plate 3" isposed on an inward 1ncl1'ne,iasat 4, 'said inclines having their lower points 1 outwardly disposed" and providing effective cam surfaces for a purpose tobehe'reinaftermoreparticposed' through end portions ofi the brace members. 71 These members 7 are ofdesired' 90 length as may be best determined byfthe requirements of practice. I

The headed member orbolt5 is positioned at a point "substantially midway of the ends of'the' 'plate 4 sothat when thebra'oe' mem- 9ibers Tare-swung into extended position' they will pass-over certain of the cam surfaces 4; with the result that-the brace members 7 are effectively- =maintained in: :their. desired extended or w;orking; position.--. Int Figure '1 these members 7 are shown as disposed in the same general direction and it will be noted that the resultant coaction with'the plate 3 maintains these brace members 7 in divergence with respect to the standard 1 so that when the device in its entirety is placed upon the desired supporting surface an effective barricade is provided and one which will readily withstand the action of the Wind.

'When the device is not in use the brace members 7 may be readily folded tolie lengthwise along the opposite sides of the standard 1 as illustrated in Figure 3 so that the device in such condition -will occupy a mlnimum of space whlch is particularly desirable both in'transportation and in storage. As particularly illustrated in Figures 2,

4 and 5,' thezbracefmembers 7 may; be disposed in opposite directions with respect to the standard 1 when the device is in use and by-having a brace 7 of one barricade crossing the adjacent braceof awsucceeding barricade and substantially incontact an elongated barricade: assembly may be obtained which will readily maintain itself in desired placement and which will also e'fiectively withstand the force, of the average wind velocity. In this particular assembly it is'to be observed that thers'econd brace member 7 of thebarricade closely approaches the cross.

member 2 of: the succeeding-barricade.

. I-fdesiredto further support the assemblyas illustrated in Figure 5; a barricade in the adjustmentlas illustrated inFigure 1 may be placed against the elongated assembly at desired point-s therealong and in lateralrelation thereto. I I We also find it of particular advantage under certain conditions to employincom nection with our improved barricadesthe attachment as illustrated in Figure 8 and which attachment comprises a plate 8 provided at its extremities and at opposite sides thereof with the upstanding arms or lugs 9 and at its central portion-with depending arms or lugs 10. I

The plate. 8 is adapted 'to be rested upon the upper end face of an upright 1 with the arms or lugs 10 extending along opposite I faces thereof. When the attachmentis ap-' only required thattwo of'our improved bars ricades be used with a board or plank con nectingsaid barricadesand operatively engagediwith the applied attachments. J If desired, a relatively long continuous barricade may be arranged by having the devices as illustrated in'Figure 1; positioned at deg an applied attachment.

sired intervals and connected by horizontally disposed boards or the like.

t is also possible with the use of our improved barricade when desired to swing one ofthe brace members or supports 7 in substantially a horizontal position with the outer or free end portion of such brace or supporting member operatively engaged with a second barricade or more From the foregoing description it is thought to be obvious that a barricade constructed in accordance with our invention is particularly well adapted for use by reason of the convenience and facility with which itmay be assembled and operated, and it will also be obvious that our invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason we do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein shown in carrying out our invention in practice except as hereinafter claimed:

lVe claim 1'. A barricade comprising a stable upright, bracing members, means for pivotally connectingsaidbracing members to an end portion of the upright, said bracing members being movable to extend either fore or aft of the upright or to be placed in collapsed,

position alongside the upright.

2. A barricade comprising an upright,

bracing members, means for pivotally connectin said bracing members to an end por-- tion ofthe upright, said bracing membersbeing movable to extend either fore craft of the upright or to be placed alongside the upright in collapsedposition, anda cross member carried by the bottom extremity of the upright and coacting with said members when extended in maintaining the upright in substantially vertical position. 7

4. barricade comprising. an upright, bracing members, means for pivotally con:

necting said bracing members to an end portion of the upright, said bracing members heing'movable to'extend either fore or aftof the upright or to" be placed alongside the upright, said bracing members being also movable to extend one on each side of the upright, and frictional means coacting with the upright'and the bracing membersfor holding'the bracing members in their various extended positions; I I
